Hypertech Max Energy Programmer Reviews


Reviewed By David R (Troy, NH) Reviewed for a 2012 GMC Sierra —4/20/2014 3:12 AM

Tire correction took 2 tries to get it right but fuel economy and shift firmness is great. I have 285/70/17 which is equivalent to a 33x11.50 and fuel mpg is a little better than stock tires but 3 mpg better than last year with these tires with out programmer. Very happy and very easy to install.

This thing ROCKS!!

This little device made a world of difference on my truck. No more 4 cylinder mode and the truck seems to shift much smoother now. My only regret was not buying this sooner.

Great little tuner

Reviewed By Roger T (Hamilton, OH) Reviewed for a 2012 GMC Sierra —5/20/2013 1:05 PM

Great little tuner By Diablo. Touch screen is a little finicky but overall I'm very happy with the product. It came with a quick guide but a full manual is available online. I gave it 4 stars based on the fact that I could not find any instruction regarding each tunable option. The Diablo tune already on the unit is quite impressive for a canned tune all the while I gained 3 mpg on city driving. I would definitely getting a Diablew custom tune to make the most of this unit.
